When TST first came out, I immediately thought it might be methoxy-test as well, in obvious relation to TRN. But the active is described as methoxy trienosterone, which leads one to believe it has 3 double bonds, an isomer of TRN. But then again that may have been the intention all along - cause extra confusion in looking for a triene.

Damn, I wish we knew the structure. I would not be uncomfortable w/ methoxy-test. But some unknown steroid with a unique triene structure, I just don't know.
